What is the difference between a mirror and a lens?

Open Ended

How do mirrors and lenses help the eye to see?

Multiple Choice

What are the 2 types of reflection?

• Polarized reflection and refracted reflection
• Specular reflection and diffuse reflection
• Direct reflection and indirect reflection
• Reflected light and transmitted light

Multiple Choice

The type of image a mirror forms depends on what?

• The color of the mirror's frame.
• The surface of the mirror.

• The distance from the mirror to the wall.
• The size of the mirror.

Multiple Choice

How do we know that the image produced by a mirror is a virtual image?

• The image can be projected onto a screen.
• The image is always larger than the object.
• The image is formed in front of the mirror.
• The image appears to be behind the mirror.

Hotspot

Which area is identifying the optical axis?

Fill in the Blanks

When rays parallel to the optical axis strike a _______ mirror, the reflected rays _______, or come together

Multiple Choice

What is the difference between a focal point and a focal length?

• The focal point is the distance from the lens, while the focal length is the convergence point of light rays.
• The focal point is always located behind the lens, while the focal length is in front of it.
• The focal point refers to the size of the lens, while the focal length refers to the type of lens used.
• The focal point is the convergence point of light rays, while the focal length is the distance from the lens or mirror to that point.
